This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.

Quad or single-digit display for E-blocks systems

This common anode, quad 7-segment LED display can be used directly with two E-blocks I/O ports to provide a high-brightness 4-digit numerical display. A jumper setting allows use of just one digit without need for using the second I/O port.

The board contains 4 power transistors to source the common anode current of each of the 7 digit LEDs. The cathode current of each segment line is sunk by the respective pins of the connected E-blocks processing board's microcontroller via 150R resistors.

This device is fully supported from within the Flowcode flowchart programming software, which makes adding an LED display to your application as easy as placing a single flowchart symbol and typing in the numbers you want to display.

E-Blocks Overview

E-Blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-Block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system.

E-Blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems.

Each E-Block has one or more 9-way D-type connectors that provide up to eight input/output lines and a ground line. These D-type connectors allow connection between E-Blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-Blocks that need it.

Processing E-Blocks based on PIC, dsPIC, ARM or AVR microcontrollers control the whole E-Blocks system. Processing E-Blocks provide up to five input/output ports with up to eight lines per port.
